I ordered LS7 lifters. I have to take everything apart anyway. Might as well replace them. I'm pretty confident this is my problem. If not, oh well, it's only $160.

Wow. Sucks you still haven't got it figured out yet.
06-15-2011
Did you pull the covers and look for oil?

I haven't been back to my parents house yet. I live and go to school on the opposite end of the city.Originally Posted by BillBoost37

When I install my new lifters and pushrods, do you have any pre-assembly tips or instructions I should follow?
06-16-2011
Soak the lifters in oil as long as you can before using them. Overnight is preferred.
Use a little assembly lube on the ends of the lifters, rods and rockers.

You may have already answered this but you are not re using the stock rocker bolts correct?
06-18-2011
No. I bought reusable rocker bolts.
06-20-2011
ur mechanic get a chance to look it over yet?
06-20-2011
No I'm going to do the lifters and pushrods first, so I can check them off the list. If this doesn't fix it, then I'll be out of ideas.
06-20-2011
when you pull the covers, check for oil. If a cam bearing spun or something else and ou aren't getting oil, the lifter can't pump the oil it's not getting.
06-20-2011
I'll check when I pull it. Could this actually be a spun cam bearing? You're scaring me.

Pulled the lower intake manifold off, and all I can say is...
Holy sh*t...
They are destroyed! How could this have happened? I'm thinking maybe this happened when my harmonic balancer was on wrong, and it turned over very poorly? I'm shocked how mangled they are.
My lifters, on the other hand, don't look too bad...
Any suggestions or opinions are greatly appreciated.
06-22-2011
Well that's your problem right there lol WOW!!!!! now you know why your compression was low.
06-22-2011
I would pull the heads and check the valves and pistons looks like your cam timing was off and shat hit the fan.
06-22-2011
My timing marks were always lined up though... How is it possible?
06-22-2011
Couldn't the harmonic balancer being off, mixed with the backfires I got, cause them to bend?
06-22-2011
yeah I remember you saying that now, I would still pull the head, and check every thing out.
06-22-2011
I just don't want to buy anymore gaskets/bolts lol. I'm a broke student, and my work just closed down for renovations. Gahhh.
I know for a fact my timing marks were always lined up. Because even after pulling the balancer off the first time (when it was on wrong), the marks were still correct.
If it messed up my pistons, and valves, along with my pushrods, my car probably wouldn't even run at all. Right?
06-22-2011
yeah, but I dont see how you bent every push rod.
